The only files Lightroom Classic can open are catalog files. When you view images in LrC, you are not looking at the original files, but previews created by LrC. Any edits you do are applied to the previews, and to a new file when you export. The original files are never changed.   To "open" (actually import) a previously imported image from the File explorer, you would have to uncheck Don't import suspected duplicates in the Import dialog. LrC will then consider this a new image, and the edits you have done to the previously imported image will not be visible. Having two versions of the same file will lead to confusion, and LrC will also become confused.   To find an image quickly in LrC, search for the file name.   ... View more

Are you telling me that even when selecting the none option, DNG Converter still embeds a JPEG (tiny) preview?   That seems to be the case, yes.   Most cameras and phones (but not all) embed a full size jpg preview in their raw files.     Are you telling me that most cameras and phones that use the DNG format for RAW, automatically embed a JPEG preview without an option not to?   I phrased that sentence badly. What I meant to say that not all embed a full size preview. For instance, my Fuji GFX 50S shoots raw files that are 8256 x 6192 pixels. The embedded previews are 4000 x 3000 pixels.   I have no experience with cameras and phones that use the DNG format. I use Nikon and Fuji cameras, and have never seen an option for not embedding a jpg preview in my cameras. My guess is that cameras from other manufacturers do not have this option either. ...

I have never used the None option for previews, but after trying it, I can confirm that it creates a small preview – 256 pixels on the long side. I have no idea why this happens. I always use Medium size, which is 1024 pixels on the long side. If you want full size previews, use the Full size option, it will stick once you've set it. Most cameras and phones (but not all) embed a full size jpg preview in their raw files.   The purpose of the jpg preview is to enable image viewers that cannot convert raw files (Photos app, File explorer, etc.) to display an image. ...

You can skip versions, no problem.   does the latest version include all of the previous version..?   The latest version does not include previous versions. Version 26 is just version 26, so if you for some reason needed version 25, you would have to install it separately. Apart from version 22, older versions (including 23 and 24) are no longer available for download, not even from Prodesigntools. Adobe's policy is now that only the current version and the previous one can be downloaded. ... View more

But i can't disable the integrated GPU because a have a second screen connected to my laptop and it's disconnect if i do that.

It's strange that the C drive crashing should corrupt catalogs on the D drive. Maybe you should check the D drive for errors. Sometimes importing a corrupted catalog into a new one can fix the corruption.

The ASUS PA248QV seems to be a standard gamut monitor (100% sRGB), so until you get your hands on a calibrator, set the monitor profile to sRGB. ... View more

Color managed software like LrC and Photoshop rely on a sound and correct monitor profile to display correct colors. This is done by converting the colors (RGB numbers) from the document profile (typically sRGB, Adobe RGB or ProPhoto) to the monitor profile. The conversion from the source profile to the destination profile is the basis of color management. A correct monitor profile is a description of the monitor's color response, and the conversion will compensate for any differences between the document color space and the monitor color space.   When you print an image, there's another conversion; from the document profile to the printing profile. To get correct colors in the print, you must use the correct profile for the printer/paper you are using.   The only way of having an accurate monitor profile is to use a hardware calibrator, like for instance this one: https://calibrite.com/us/product/display-plus-hl/ Using a calibrator involves a two-step process – first there is calibration, which adjusts your monitor into a state suitable for profiling – then a custom monitor profile is created, installed, and set as default. If you have several monitors, each one has to calibrated individually. ... View more

I'm glad you got it sorted. However, there is no need to use the Advanced tab of the Color management dialog. In fact, the usual advice is to leave it alone. Apparently, not even Microsoft engineers can explain what it does. But I believe that the default for Device profile is sRGB.   The monitor profile is set in the Devices tab, and you have to check Use my settings for this device to be able to add profiles. If you have a laptop plus an external monitor, they will be listed as separate devices, and each need a separate monitor profile. If your laptop screen is standard gamut, you should set it to sRGB. If it is wide gamut, you should set it to Adobe RGB (not Wide gamut RGB). This also applies to the external monitor.   I'll try to get back to you tomorrow with some more advice on color management and calibration. ... View more

There is absolutely no obligation to try suggestions and respond straight away, do it when you have the time and energy. I'm in the same time zone as you BTW, and sometimes I'm unable to answer questions during daytime.   Software issues tend to happen all of a sudden. For instance, Windows updates sometimes install monitor profiles from monitor/laptop manufacturers. These profiles tend to be low quality, and are very often defective out of the box. LrC is very picky about the monitor profile, and a bad profile can manifest itself in different ways, one of them is displaying grey boxes instead of thumbnails. Also, LrC can trip over a monitor profile that Photoshop has no problems with.   If my two latest suggestions don't work, try resetting the LrC preferences. https://helpx.adobe.com/lightroom-classic/help/reset-preferences.html ...

Your GPU driver is out of date. You have version 572.16, the latest version is 576.52. Download the latest studio driver from this page, then install it. https://www.nvidia.com/en-us/drivers/details/245675/   You also seem to have an integrated GPU (Intel UHD Graphics 630). Make sure that it's disabled in the Device manager. Adobe software does not work well with dual GPUs. Open the Windows Control panel, then click Device manager.     Click Display adapters, then right click the Intel UHD Graphics 630 and choose Disable device. Do NOT disable the NVIDIA GeForce GTX 1050 Ti, just leave it as is. The screenshot below is just an example from my own computer.

Hello everyone, I've been talking in English with technical support for two weeks, since all of a sudden the previews of the Library section have stopped being shown. Like when I try to import new images, it doesn't show up either. The thing that in the Develop window does show the images but doesn't let me edit photos, since it does weird things and doesn't save the changes. The technical service has done everything, look at my cache, the space in Lightroom, give me permissions to all the admins related to Adobe, they have created a new catalog and have sent it to the technicians, who at first forgot to send me, and when I complained again for the third time they sent it to me. It has not worked either, today I have spent an hour and a half writing with another technician who has even uninstalled the program, has installed later versions, copied or rather duplicated folders to my desktop, in case the problem came from my Hard Drive and I have tried many of my catalogs that I have and the problem continues... I don't know what to do, he has suggested that I reinstall Windows, but I think it's too much already. I don't have a virus... I NEED HELP!! I have a lot of work to edit. I know I have Camera RAW but when you have a lot of photos like I do now that editing and presenting a project in a month, it's very slow. Has it happened to someone, someone comes up with something or do you have computer friends who can give me a hand?? If you need screenshots I will upload them but I think I have explained myself...  By @NachoSM   Please go to Help > System info in LrC, click the Copy button, and paste in a new reply. ...
